Abstract:Â The project deals with the experimental study on the performance of high strength concrete by application of pre-tensioning to the concrete before concreting. In case of structural elements which are subjected to high stressing or loading can be made sustained by making the structural element able to with stand the imposed load. In this study, a high strength mix of M40 were casted where in other specimens were made with the help of applying the pre-stressing by stressing cables in single and double profile and casted after initial stressing in done. Because of applying pre-stressing, the element behaves in such a manner to develop its ability to withstand a higher load than the concrete specimen made out of control mix. The performance of this element casted will show a unique behavior than the control mix under flexural stress. The comparative study of the pre-stressed and plain concrete is studied experimental and their corresponding results were obtained.
This study will exhibit the ability of pre-stressed concrete over the plain concrete. It is expected to know the different types of construction procedures that are to be implementing, and different types of design mixes for designing of beams. It is also expected to know the procedures adopting for different techniques for casting of the pre-stressed beams. Thus it can be concluded that pre-stressing provides a means for the most efficient use of concrete.
